Add a specific proposal for the SMP networking project.
This proposal is built on top of several individual, smaller projects, all
of which are related to achieve the goals of SMP support and modularity on
the network stack. Keep in mind that this is just that: a proposal.
Applicants could still come up with their own ideas.
The text of all these new pages is mostly a copy/paste of the original
document written by matt@ (see http://www.netbsd.org/~matt/smpnet.html).
I have done some minor edits (hopefully not changing any of the technical
details) and added some preliminary texts to the pages. (I was unable to
parse some of the sentences though, so they remain "as is"...)
